COELDI'S MARMOSET. 



Type locality. Para, Brazil. Brought alive to the city. Type in 

 British Museum. 



Genl. Char. Hair on back and shoulders long, silky, projecting 

 beyond ears. 



Color. Head, limbs and upper parts blackish brown, the hairs 

 at base are broccoli brown graduating into black, and tipped with pale 

 brown ; white tufts exist on head in front of ears, and on either side 

 of the back at the loins, and there are white hairs scattered about the 

 forehead ; feet, hands, under parts and tail black, with light tips show- 

 ing on some of the hairs in the tail. Ex type British Museum. 



No skull to the specimen. 



The specimen is in poor condition and misshapen, so that it would 

 be impossible to give correct measurements. The skin of the hands and 

 feet has been filled with some material and is stretched, making these 

 members appear unusually broad, and the skin of the body has been 

 shortened in making up. There is no species of the genus known to me 

 to which this specimen can be assigned, but as the animal had been in 

 captivity, and possibly, as suggested by Mr. Thomas, had been injured, 

 this accounts for the white hairs on different parts of the head and 

 body. We must wait for additional examples to enable us to decide 

 what shall be its proper place in the genus.
